The history of the place starts in the Bronze Age (from 1400 to 700 BC) where the first habitats for human settlements were evolved. It was in this epoch where the hallmark of Duingt, the island called the island of Roselet, has been evolved from the lake. The first prehistoric objects such as pieces made of ceramic, bracelets and rings which are exhibited at the museum of Annecy have been found in 1856. Further pieces which relate to prehistoric settlement have been exposed in 1860.
The church of Duingt was built in the 19th century in Neo-Gothic style. Duingt has two castles, but they can not be visited. The Château de Duingt (other names: Château de Châteauvieux or C. de Ruphy) is located on a small island connected by a causeway to the mainland. The original castle was built in the 11th century and got its present shape between the 17th and 19th centuries. In Dhéré you can find the Château d'Héré built in the 15th century. In the center of Duingt there are still a number of houses in the typical Savoyard style of the 17th and 18th centuries.
